    Switching 35V, 500 mA with digital output?

    I am getting some very good feedback, but I realize that I need to provide a little more information about my application in order to get more specific information. I need to control a DPDT mechanical relay to switch a 35 V, 500 mA constant current programmable supply between 2 different...

    Controlling 12VDC fan using digital output on DAQ

    If your DAQ card has a general purpose counter output, you could use it to drive a mosfet and vary the fan speed by varying the duty cycle of the counter output. If you only need on/off control, you could use a 5V digital output to drive a transistor. I have used both of these approaches with...
